Professional service for Wacker Neuson equipment

### Repair and Diagnostics of Wacker Neuson Equipment

Compact Wacker Neuson equipment is famous for its incredible jobsite performance, but even the most refined machines require regular technical care. At **WIBAKO**, we provide full-scale repair services, conduct precise field diagnostics, and carry out thorough component overhauls. Our specialists excel at handling complex power hydraulics from respected suppliers, as well as efficiently restoring Yanmar, Perkins, or Deutz powertrains to full operational condition. Our main workshop headquarters is located in Kojszówka, from where we serve clients across all of Poland.

We know the design specifications of virtually every model from this manufacturer—from popular mini-excavators (such as ET18, ET24, or 803) and agile wheel and articulated loaders (e.g. WL20, WL32), to high-performance site dumpers, compactors, and rollers. WIBAKO's strength lies in the synergy of engineering knowledge with modern machinery facilities. All remanufactured multi-piston pumps, control valves, and travel motors undergo rigorous pressure testing on a stationary test bench, ensuring that the delivered component will withstand the highest loads.

Remanufacturing and troubleshooting for internal combustion engines

### Engine Repair for Wacker Neuson Machinery

Power loss, disturbing exhaust smoke, sudden drop in compression, or starting issues? Instead of quick fixes, WIBAKO offers technically sound, long-term solutions. Our dedicated team of engine mechanics focuses exclusively on complete overhauls of powertrains installed in Wacker Neuson machinery. We recondition Yanmar, Perkins, and Deutz engines, ensuring precise adherence to all design tolerances.

The rebuilding process in our workshop is fully transparent. We disassemble the engine down to the last component, clean it in chemical baths, and perform a detailed wear inspection on each individual part. We surface cylinder heads, recondition crankshafts, install brand-new piston-cylinder assemblies, and precisely calibrate injection systems.

Guarantee of full operational readiness

### Diagnostics on a Stationary Engine Dynamometer

We feature a modern stationary engine dynamometer (with capacity up to 500 HP), where we test every rebuilt engine. Instead of assumptions and projections, we rely on hard measurement of parameters under real working load.

The load test process on our dynamometer simulates the toughest working conditions faced by Wacker Neuson equipment. During a multi-hour test, we record in real time:

Current power output generated by the engine and torque values

Pressure and temperature ranges of oil and coolant in the cooling system

Smoke level and exhaust gas temperatures

Combustion stability, fuel consumption, and absence of any leaks

### Complete Safety

### 12-Month Warranty Protection

We are confident in the high standards maintained in our workshop, which is why after a complete engine overhaul we offer a full **12-month warranty** with no operating hour limits. This provides a secure safety buffer for your business and guarantees trouble-free operation of Yanmar, Perkins, or Deutz machines working under the Wacker Neuson brand.

When to request an engine diagnostics?

### Signs of Engine Damage in Wacker Neuson Equipment

Wacker Neuson construction and compaction equipment often operates under high loads in extremely dusty environments. Ignoring early symptoms of a fault can quickly lead to severe engine seizure.

**Pay attention to the following warning signs:**

**Changed exhaust smoke color -** black clouds under load indicate issues with injectors or the turbocharger, blue smoke signals piston ring wear and oil burning, while light/white smoke indicates a head gasket leak.

**Noticeable power loss -** mini-excavator or loader loses power when digging into ground, and engine RPM drops sharply during simultaneous functions.

**Starting difficulty -** prolonged cranking with the starter motor, both on a cold engine overnight and on a warm engine during the day.

**Unstable idling and knocking -** uneven idling rhythm and hard knocking sounds originating from the cylinder block.

**Severe crankcase blow-by -** visible smoke or oil spitting when removing the oil filler cap or coming from the engine breather.

**Operating fluid loss -** disappearing coolant or rapid drop in engine oil level despite no visible external leaks.

Hydraulic power system service and remanufacturing

### Experienced WIBAKO Power Hydraulics Department

Within the WIBAKO structure operates a separate, specialized department of mechanics handling exclusively power hydraulics. They possess extensive knowledge regarding the construction of axial piston pumps, travel motors, swing motors, and control valves fitted in Wacker Neuson machines.

After disassembling a component, we perform meticulous micromeasurements of valve plates, pistons, bearings, and housings. Thanks to a vast inventory of spare parts available in our warehouse, we replace worn parts off-the-shelf. This minimizes remanufacturing downtime and significantly reduces costs compared to purchasing new hydraulic assemblies.

Professional hydraulic test bench

### Test Bench Diagnostics

Accurate fault localization in the hydraulic system guarantees a successful repair. We have extensive diagnostic stations and a stationary hydraulic test bench, allowing us to thoroughly check hydraulic pumps and motors prior to mounting them on the target machine.

We measure key indicators—flow, working pressure retention, and internal leakage under maximum load. Test bench verification eliminates the risk of defects and ensures that hydraulics in your Wacker Neuson machine will operate with factory precision immediately after installation.

### Hydraulic system failure symptoms

### When Does Wacker Neuson Hydraulics Require Service?

Hydraulic systems are responsible for the machine's responsiveness and power. Early detection of performance drops protects the entire system from contamination caused by metal shavings from wearing parts.

**Key symptoms of hydraulic wear:**

**Performance drop as temperature rises -** the equipment operates correctly upon startup, but as the oil heats up, movements become slow and lack power.

**Loss of lifting capacity and breakout force -** the machine cannot lift a full bucket or close the attachment, accompanied by loud squealing from main relief valves.

**Travel problems -** the mini-excavator pulls to one side during travel or struggles to climb a slight incline.

**Sluggishness of individual functions -** lack of smoothness or total loss of a single working motion while other functions operate normally.

**Metallic noise from the pump -** loud grinding or knocking around the main pump, most commonly caused by cavitation or galling of rotating parts.

**Oil overheating -** hydraulic fluid reaches very high temperatures quickly, losing lubricating properties and damaging seals.

**Metal shavings in reservoir and filters -** metal particles on the hydraulic filter element signal an immediate shutdown of the machine before complete system destruction.
